It can't be 100% accurate, but they used good criteria to find buildings.
A seismic engineer did not go to every building that was potentially considered to be an Unreinforced Masonry Building (URM), but the criteria used is a good one for future research (since that is cheaper than actually doing something to make the buildings safer).
The map allows people to sort by location and type of use for the building, e.g., schools. With the legislative session wrapping up soon and the deadline for new bills having passed, there will be no further action this legislative session. So we now have time to contemplate our respective navels until the next legislative session.
Likely, we can postpone action for another few years. A little shaker might move things along — but then, it had better happen early in a legislative session to spur some form of action.
